Answer 1

I can’t answer from the text alone because I don’t see the Venn diagram or the numbers in its regions. Please either upload the diagram or type the numbers in each region.

How to get the answer once I have the diagram:
- p ∧ r true and q false means the teachers in the region p ∩ r ∩ ¬q (the part where p and r overlap but outside q).
- Read the number in that single region (or, if the diagram gives counts for larger combined regions, compute p∩r minus any who are also in q).

If you post the diagram or the region counts I’ll give the numeric answer.
